DESCRIPTION

Oki’s 0.25µm Application-Specific Integrated Circuit (ASIC) products are available in both Sea Of Gates (SOG) and Customer Structured Array (CSA) architectures. Both the SOG-based MG115P series and the CSA-based MG75P series use a five-layer metal process on 0.25µm drawn (0.18µm L-effective) CMOS technology. The SOG MG113P/114P series uses the same SOG base-array architecture as the MG115P series, but offers four and three metal layers, respectively. The MG73P/74P CSA series uses three and four metal layers, respectively. The semiconductor process is adapted from Oki’s production-proven 64-Mbit DRAM manufacturing process.

FEATURES

• 0.25µm drawn 3-, 4-, and 5-layer metal CMOS

• Optimized 2.5-V core

• Optimized 3-V I/O

• SOG and CSA architecture availability

• 77-ps typical gate propagation delay (for a 4x drive inverter gate with a fanout of 2 and 0 mm of wire, operating at 2.5 V)

• Over 5.4M raw gates and 868 I/O pads using 60µ staggered I/O

• User-configurable I/O with VSS, VDD, TTL, 3-state, and 1- to 24-mA options
